🤔What is a total solar eclipse? 🔜A total solar eclipse happens when the Moon passes directly between the Sun and Earth. The Moon blocks light from the Sun and casts a shadow on Earth. Find out more www.esa.int/Science_Expl... #EuropeanSolarEclipse

“What a beautiful universe, hon" says a telescope as gazes upon an aurora borealis. “It really is”, responds the telescope's partner, who it turns out is not a telescope, but a microscope. Hands full of algae, she wades waist deep in a disgusting swamp, amazed by the heavenly microscopic life all around them.

This visualization simulates what the crew of Artemis II will see out the window on the day of their closest approach to the Moon on April 6, 2026. It covers the period of their scheduled science observations that begins at 18:45 UTC and spans seven hours, flying the virtual camera on the actual post-TLI trajectory that swings the spacecraft around the Moon's far side.

If you’re watching the #Artemis II livestream you’re probably hearing the word “albedo” a lot, but what does it mean? It’s simply a measure of how reflective a surface is. If a surface absorbs all incoming radiation it has an albedo of 0, if it reflects all of it albedo is 1 (1/n) 🧪🔭

NOAA Space Weather Scale descriptions can be found at

Potential Impacts: Area of impact primarily poleward of 45 degrees Geomagnetic Latitude.
Induced Currents - Possible widespread voltage control problems and some protective systems may mistakenly trip out key assets from the power grid. Induced pipeline currents intensify.
Spacecraft - Systems may experience surface charging; increased drag on low earth orbit satellites, and tracking and orientation problems may occur.
Navigation - Satellite navigation (GPS) degraded or inoperable for hours.
Radio - HF (high frequency) radio propagation sporadic or blacked out.
Aurora - Aurora may be seen as low as Alabama and northern California.:Product: 3-Day Forecast

A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 4 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Jan 19-Jan 21 2026 is 8.00 (NOAA Scale
G4).

NOAA Kp index breakdown Jan 19-Jan 21 2026

             Jan 19       Jan 20       Jan 21
00-03UT       3.33         5.00 (G1)    4.33     
03-06UT       1.67         5.67 (G2)    4.67 (G1)
06-09UT       0.67         8.00 (G4)    4.00     
09-12UT       1.00         5.67 (G2)    3.00     
12-15UT       3.33         6.67 (G3)    2.33     
15-18UT       3.33         6.00 (G2)    2.67     
18-21UT       3.00         5.33 (G1)    2.00     
21-00UT       4.33         5.00 (G1)    3.00     

Rationale: G3-G4 (Strong-Severe) geomagnetic storms are likely on early
on 20 Jan due to the anticipated arrival of a halo CME that left the Sun
on 18 Jan.

B. NOAA Solar Radiation Activity Observation and Forecast

Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was
above S-scale storm level thresholds.

Solar Radiation Storm Forecast for Jan 19-Jan 21 2026

              Jan 19  Jan 20  Jan 21
S1 or greater   99%     95%     65%

Rationale: S1-S3 (Minor-Strong) solar radiation storms are expected to
continue through at least 20 Jan. With S1 (Minor) conditions likely on
21 Jan due to influence from an approaching CME.

C. NOAA Radio Blackout Activity and Forecast

Radio blackouts reaching the R3 levels were observed over the past 24
hours. The largest was at Jan 18 2026 1809 UTC.

Radio Blackout Forecast for Jan 19-Jan 21 2026

              Jan 19        Jan 20        Jan 21
R1-R2           65%           65%           65%
R3 or greater   20%           20%           20%

Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely, with a
slight chance for R3 (Strong), over 19-21 Jan due primarily to the flare
potential from Region 4341.
